BoneSlicer
Experimental G-Code-Generator for variable density infill in FFF parts
BoneSlicer is an experimental G-Code-Generator written in Java that allows creating load-adapted infill for 3D printed (FFF) parts, inspired by the adaptive structures of trabecular bone tissue. It uses a simple structural Finite Element Analysis to determine the distribution of mechanical stress within the part and offers tools to generate an infill structure consisting of multiple subareas of varying infill density. Subdivision of the infill area can be based on a broad spectrum of FEA result... -

OGFEM1d
A simple one-dimensional example of the OGFEM
We apply the Orthonormalized Generalized Finite Element Method (OGFEM) to the one-dimensional inhomogeneous modified Helmholtz equation and compare its performance with the traditional Finite Element Method (FEM). The OGFEM avoids loss of accuracy by modifying the basis such that it results in a system matrix with a condition number which is significantly lower in comparison with the condition numbers obtained by the GFEM/XFEM or SGFEM/SXFEM. Consequently, enriched basis functions can... -

MT2D
An 2D magnetotellurics finite element solver using unstructured grids
MT2D is a two dimensional magnetotellurics or raido magnetotellurics forward modeling software. In terms of unstructured grids, it can deal with arbitrarily complicated models, including the surface topographies. It allows for arbitrary distributions of conductivity, permittivity and permeability. In addition, it offers two algorithms: the total field approach and the secondary field approach. At present, most of 2D MT modeling codes are developed in terms of Matlab or FORTRAN and... -
